Who is Sergei Kopeikin?

Sergei Kopeikin is a USSR-born theoretical physicist presently living and working in the United States, where he holds the position of Professor of Physics at the University of Missouri in Columbia, Missouri. He specializes in the theoretical and experimental study of gravity and general relativity. He is also an expert in the field of the astronomical references frames and time metrology. His general relativistic theory of the Post-Newtonian reference frames which he had worked out along with Victor A. Brumberg, was adopted in 2000 by the resolutions of the International Astronomical Union as a standard for reduction of ground-based astronomical observation. In September 2002 he led a team which conducted a high-precision VLBI experiment to measure the fundamental speed of gravity. He is also involved in studies concerning the capabilities of the Lunar Laser Ranging technique to measure dynamical features of the General Theory of Relativity in the lunar motion. He has recently criticized the claims of other scientists concerning the possibility of LLR to measure the gravitomagnetic interaction. Prof.
